TO ALL WHOMIT MAY CONCERN:

Be it known that I, P. ATKINSON ROSS, of Harveys, in the county ofGreene, and State of Pennsylvania,` i

have invented a. new and useful Improvement in Shovel-Ploughs,Cultvators, 86e.; and I do hereby declare that ,the following is a full,clear, and exact description thereof, which will enable those skilled inthe art; to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which- ,p

Figure `1 is a top view of a single-shovel plough, illustrating myinvention.

Figure 2 is a detail cross-section of the same, taken through the lineai z, fig. 1.

Similar letters of reference indicate corresponding parts.

My invention has'for its object to improve the construction of singleand double-shovel ploughs, cultivators, Ste., so as to enable them to bereadily adjusted for use upon side-hills or level gronnd, so that thehandles may be secured in nearly a. level position, while the plough isheld in the best position for doing'its work properly; and it consistsin the manner in which the cross-bar is adjustably secured to thestandard, and in the manner in which `the forward ends of the handlesare connected tothe beam the whole being constructed and arranged ashereinafter more fully described. v

A is the beam of the plough, to the rear end of which the standard B isrigidly and securely attached. C

is the cross-bar, which passes through a slot in the standard B, and tothe ends of which the handles D are attached. The slot through thestandard B is made so large that the cross-bar C may rockA in it, andthe said p cross-bar is secured and pivoted in place by the pin e', thatpasses through the standard B, and through'the cross-bar C, below itscentral point, as shown in fig. 2. To the upper side of the cross-bar C,at its central part, is attached a rack, E, having three, or some otherodd number of notches formed in it, as shown in iig. 2, so that the saidcross-bar may be secured in a horizontal or inclined position, accordingas it is desired to have the plough work upon level ground or upon aside-hill. The cross-bar C is secured in place when adjusted, by a. pin,F, passing through the standard B, and through one or the other of thenotches of the rack E. Upon She ends ofthe cross-bar Care formed roundtenons, which pass through holes in the handles D, so that the saidhandles may have a slight movement upon the said cross-bar. To theforward ends of the handles D are attached hooks or eye-bolts, G, bywhich the forward ends of the said handles are pivoted to the ends ofthebar or plate H, which is pivoted at its centre to the beam A, as shownin fig. 1, so that the said handlesmayV readily adjust themselves,according to the positionof the cross-bar O.

I claim as new, and desire to secure by Letters Patent-y 1. Thecombination of the notched rack E and removable pin F, withthe pivotedor rocking cross-bnr C and slotted standard I3, substantially as hereinshown and described, and for the purpose set forth.

2. Connecting the forward ends of the handles D to the beam A, by meansof the hook or eye-bolts -G and pivoted bar or plate II, when used inconnection with the pivoted or rocking cross-bar C and pin F,substantially as herein shown and described, and for the purpose setforth.

I. ATKINSON ROSS.
